This is an undescribed species of Chromodoris. Chromodoris tinctoria is reported to have the red spots on white and a yellow margin, and not to have all the other dorsal coloration around the red spots.

This is an extremely interesting individual. It seems to have some black pigment at the very base of the inside of the gill axes which relates it to the western Indian Ocean Chromodoris boucheti. But in true Chromodoris boucheti there are black lines running the full length of both axes. It is probably an undescribed species.

An undescribed species. The simple dorsal pattern of black lines is like that seen in Chromodoris lochi, but the sky blue colour (instead of white in Chromodoris lochi) and yellow-orange rhinophores and gills (instead of pale pink as in Chromodoris lochi) are consistently different. So I agree with Kuiter and Debelius (in their new book Nudibranchs of the World page 176) that this is an undescribed species.
